What are the basic functions of the operating system? [4] Hide backstage operation and algorithm and instead present simplified user interface. Management of resources Software and hardware manipulation data management and calculation conversion and transfer between software and hardware
When we run out of memory, what will the operating system do? What is this mechanism called? How does it work? [3]
The computer system will transfer the pages of data from RAM to disk storage. Virtual memory. It stores the page data in disk when memory is running out, then when the memory is freed up, the operating system will retrieve the data that was moved to disk storage
When clicking the mouse, what happens to your computer system? [3]
The operating system will carry out an interrupt, notifying OS with a parameter indicating the lag of the button, in this case the mouse click, along with coordinates of the mouse.
